AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
300 AM MDT THU JUL 10 2008

.SHORT TERM...TODAY THROUGH FRIDAY...DEFINITELY A RED FLAG DAY WITH
VERY LOW RH INTO THE SINGLE DIGITS IN SOME AREAS...WIDESPREAD WIND
GUSTS IN EXCESS OF 30 MPH...AND DRY ENOUGH FUELS IN ALL BUT THE
FOREST AREAS OF THE WEST CENTRAL AND BOISE MOUNTAINS. AS THE UPPER
LEVEL LOW TRACKS EAST ACROSS WESTERN CANADA THE ASSOCIATED STRONG
JET WILL SUPPORT PLENTY OF SUBSIDENCE TO MAINTAIN VERY DRY AIR OVER
OUR CWA. FOLLOWING THE SURFACE FRONT LATE THIS AFTERNOON PRESSURE
GRADIENTS ENHANCED BY MID LEVEL FLOW WILL SUPPORT STRONG GUSTY WINDS
ON THE OREGON SIDE SPREADING ACROSS OUR IDAHO ZONES THIS EVENING.
WINDS WILL CONTINUE THROUGH THE NIGHT AND ON FRIDAY ALTHOUGH NOT AS
STRONG. TEMPERATURES TODAY WILL BE SIMILAR TO YESTERDAY. FOR HIGHS
FRIDAY WE PREFER THE SLIGHTLY WARMER ADJUSTED GFS AND MET GUIDANCE
WHICH COOL TEMPERATURES TO NEAR NORMAL.

.LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY...LITTLE CHANGE FROM
PREVIOUS FORECAST WITH MODELS REMAINING IN GOOD AGREEMENT ON DRY
CONDITIONS AND ABOVE NORMAL TEMPERATURES FOR SATURDAY AND SUNDAY.
HEIGHTS AND THICKNESSES REBOUND AFTER THE COOLER WEATHER FRIDAY BUT
NOT OF THE MAGNITUDE TO BRING TRIPLE DIGIT READINGS TO THE FORECAST
AREA. MONSOON MOISTURE BEGINS TO GATHER OVER THE SOUTHWESTERN U.S.
EARLY NEXT WEEK AS A LARGE AND INTENSE UPPER RIDGE DEVELOPS OVER THE
FOURS CORNERS REGION.  THIS IS PRETTY MUCH IN ITS CLIMO POSITION FOR
THIS TIME OF YEAR. MODELS STILL UNCERTAIN IF THIS MONSOON MOISTURE
WILL BEGIN TO WORK NORTH ON SOUTHERLY FLOW OR HOLD IN POSITION OVER
THE SOUTHWEST. ANY NORTHWARD DRIFT OF MOISTURE FROM THE SOUTHWEST
WOULD GIVE RISE TO AN INCREASED SHOWER AND THUNDERSTORM THREAT...BUT
FOR NOW MOST OPERATIONAL MODELS HOLD WITH DRY CONDITIONS FOR OUR
AREA.  TEMPERATURES NEXT WEEK RUNNING JUST A LITTLE ABOVE NORMAL BUT
NOT THE EXCESSIVE HEAT WE HAVE EXPERIENCED IN THE PREVIOUS JULY
YEARS.

&&

.AVIATION...VFR CONDITIONS UNDER CLEAR SKIES THROUGH THURSDAY. SMOKE
FROM FIRES IN CALIFORNIA WILL KEEP LOWER VISIBILITIES OF 6 TO 10SM
UP TO 10K FEET MSL IN LOCAL AREAS OVER SOUTHERN PARTS IDAHO AND
OREGON EARLY THIS MORNING. AN INCREASED WEST AND NORTHWEST WIND FLOW
ASSOCIATED WITH A COOL FRONT THIS AFTERNOON WILL QUICKLY SWEEP THIS
SMOKE WELL EAST AND AWAY FROM THE AREA THIS AFTERNOON. EXPECTING
FROPA BETWEEN 21Z AND 23Z WITH WESTERLY WINDS INCREASING 15 TO 20
KNOTS GUSTING TO 30 KNOTS THROUGH 03Z.
